Network Control and Monitoring
Inverter Control Sequence 2 – In this second sequence, the DeviceNet host computer
will control the inverter (Run/Stop) and also provide values for output frequency / accel /
decel (overrides F_01, F_02, and F_03). This sequence assumes that you have success-
fully completed Control Sequence 1 on the previous page.
a. Confirm that the motor is stopped.
b. Turn ON the Network Reference bit (bit 6) in Word 0 as shown below. This
indicates to the inverter that the network will supply real-time profile values for
output frequency / accel / decel. (The Network Control bit should still be ON.)
DO NOT turn on the FW Run bit (bit 0) yet.

c. Refer to the values for Word 1, Word 2, and Word 3 listed below. With the host
computer, set the values as indicated.
Word 1 (Output Frequency) = 2000 decimal (20.00Hz)
Word 2 (Acceleration time) = 100 decimal (10.0 seconds)
Word 3 (Deceleration time) = 100 decimal (10.0 seconds)
The host computer's polled I/O output data should match the values below.
Word 0
Word 1
Word 2
Word 3
NOTE: The scaling of the polled I/O data for output frequency /accel / decel values
corresponds to the network scale factors for parameters F_01, F_02, and F_03, respec-
tively. A listing of inverter parameters and scale factors is in the "Network Register
Map" on page 78.
d. Turn ON the FW Run bit (bit 1) in Word 0 as shown below. The motor will now
begin to run. The output frequency will be 20.00Hz. To verify the motor speed,
monitor D_01 on the inverter display, or use the host computer to observe the
actual output frequency reported in the polled I/O.
